Thanks for updating in! This is not a conflict with WooCommerce and the theme. Please keep in mind that as soon as you assign any page as your shop page, you cannot edit it with Cornerstone. WooCommerce runs its own template which is why it is no longer possible to edit the content in Cornerstone.
If you will need to edit the page, you may deactivate WooCommerce or unassign the page as your shop page and re assign it again after making the changes.
Hope this explain it briefly.
